ok seems like we got the idling issue down after messing with the throttle body we got the voltage to about .68 and the car seems to be running fine... except when you put it into any gear, turn the A/C on, turn the wheel (power steering)... then the car just hesitates and dies.. any ideas

 

idle too low?

In gear, a/c on, and p/s pump pulling all at the same time is alot of load..

 

well i dont use it all at once sorry i should have clearified it its if im using one or the othere but once i put it in gear car studders like crazy then dies

 

Can you keep it alive enough to try to drive it? Sometimes it takes a bit for the car to learn its proper idle.

Clean your IAC?

Took a couple of startups for my car to keep an idle w/ the recent build, but it stays on most of the time now.

 

cant keep it alive at all in gear it sucks man especially when u dont know what the heck it can be i can try cleaning it or replacing it all together any othere ideas and hows the car runnin for ya

 

My car is running well, see this thread for mine so i don't hijack yours

Try clearing your PCM. Also, when you fire it up in Park will it at least rev up smoothly to about 3500-4k or so?

 

I dont know about your tune but I would set the idle through the pcm first then the idle screw.

 

Get your IAC counts to ~40 at hot idle and then slot your TPS so you can get it to be about .5v at closed throttle. If this isn't adjusted properly, the car will do exacly what you are describing.

 

hmm set it .5v isnt that too low? and my tune was just recently done by pcmforless hmmmm i appriciate all the feedback and the pcm and i cleared all the codes how do u adjust the iac? sorry for being such a dumb*** when it comes down to this

 

oh yea and yes when its in park i can rev it to whatever rpm i want to achieve

 

Does anyone have a write-up for slotting the TPS? I think my car would die if the IAC's were in the 60's.

 

For slotting the TPS, take it off of the car, use some sort of a cartridge roll or grinding head on either a Dremel tool or die grinder that will fit in the original bolt holes and turn the holes into slots that maintain a constant radius from the centerline of the sensor.


For adjusting the IAC, just hook up a scanner and use the throttle adjust screw to get the counts where you want them. Then turn the engine of (KOEO) and adjust your TPS while watching the voltage on a scanner or probing the connector.

 

hmm hope this works ill keep you guys posted on it if anyone else has any opinions go right ahead im open for suggestions

 

Resetting IAC........

Not SURE this is what you're look for but maybe it will help. http://shbox.com/1/4th_gen_tech2.html#iac_reset

 

whats the trick to bringing down the iac's? I tried everything all night!!!!
